FASTENING nnvrcn.

To all whom it may concern,"

citizen of the United States, residin at Bristol, in the county of Hartford and tate of Connecticut, have invented certain new anduseful Improvements in Fastening'De woes, of WlllClI the following is a specifica tion. 7

This invention'relates to fastening de-" vices intended more particularly by me for use as part of an anti-skidding or traction 1 unit of the anchored or fixed point type for motor truck wheels, especially tothat type of such devices employing a pin or bolt and resides especially in the special construe tion of the pin and the means for locking the same in position.

The chief objects are to provide a pin for suchdevices of uniform diameter from end to-end, excepting for an annular groove near its lower end, without head or tip, in or'der that it'may be formed from ordinary commercial stock simply by cutting off the 5 requisite length, grooving and applying the stop pin, thereby greatly reducing the cost paratus in a given time than heretofore and to provide a catch to retain said pin in normal position, which catch 'is "provided with means for looking it in normal position against jars and other actions and forces tending to accidentally displace it, but which yields to intentional intelligently applied force, and is so formed and mounted in relation to a relatively fixed part that it cannot be moved beyond a certain point, thereby guarding against its flying outward in its movement at right angles to said fixed object during the rotation of the wheel and being so damaged by the walls of ruts or objects on the road as to make it impossible tomove said catch back into normal position again. 7

Other objects are to provide means'for' easily moving the'pin out of normal posio he ar accgimplis d by the COHSH'HQ15 a common axial line.

tion, combination and arrangement of" Be it known that I, AsHLEY L. Brsrror, a

parts all as-hereinafter more particularly set forth, described and claimed.

In the accompanying drawings: Figure 1- represents: a front elevation of a-clamp applied to a spoke; of awheel and away, taken through the lower 'flangeof'thei primary plate in'the'plane of the catch andlooking upward, showing the, catch in normal position in solid llnes and in open position in dotted lines;

Fig. 5, a vertical sectional view on the line 55 of Fig. i;

Fig. 6, a similar view on the line 66 of Fig. 4; U -1 i I Fig. 7, a similar view on the'line 77 ofr Referring now in detail to the drawings, A indicates'the front plate of a two plate clamp having a rubber treated lining B and provided with perforated end flanges G for. thereception of bolts D on which nuts are to be turned to draw the two plates together on the outer portion ofa spoke E f of the wheel with the 'fiange 2 of plate A adjacent the inner face of the felly F, on which is mounted the tire G. I H indicatesone of the transverse traction or anti-skiddingchains of the fixed point or anchored type.

The plate A is provided with two parts or flanges 1 and'Q, preferably, though not necessarily, integral therewith and preferably parallel to each other. Each flange is perforated asishown in Fig. :5, the perforations being of the same diameter and having escape of foreign matter to prevent the slot 3 from becoming clogged up, and has a verticalbore 5. conununicating'withsaid slot 3,

and a hole in its outer portion extending j through said slot 3.

A keeper 6 is mounted insaid 51 i; 3 by means of a rivet :7 passing through the above mentioned hole and is provided'with a de the flange 1, excepting at the inner end po ,tion of said catch 6, at which point it s pressed lug 8 snapping into the bore 5 above mentioned. This keeper is formed of resilient metal and is slightly deformed or twisted in forming the lug 8, as illustrated in Fig. 6, so thatit bears against the lower wall of the slot 3 near its outer end and against the upper Wall of slot 3 near its inner end, obtaining a good frictional engagement and forcing said lug 8 in said bore as the catch is moved to normal position and firmly holding said lug S in said bore 5, preventing the accidental catch. V f 7 Theouter end and the side edges of said catch preferably are fiush'with the edges of provided With a projection 9 to be'engaged by a screw-driver or other convenient tool to force it into open position, indicated by d0tted lines in Fig. 4.

The inner wall of the slot 3 at its outer end portion is preferably straight, as is the outer end portion ofthe inner edgeof the catch 6, which edge portion of said catch preferably lies parallel to the inner wall of the outer portion of slot 5 when the catchisin normal position, and the rivet 7, forming the. fulcrum for the catch 6 is so positioned with relation to the inner wall ofthe slot 3 that when said catch 6 is movedthereon outwardly the tip of the outer'portion of its inner edge will abut against the correspond' ing portion of the inner wall ofslot 3, as shown in dotted lines in Fig. 1, thereby preventing the further opening movement ofv said catch.

The inner edge of said catcli6 is also provided with a cam-face normally extending into the perforation in said, flange l as shown in Fig. lin solid lines, but lying outside thereof when the'catch is in open position, as shown in dotted lines in said figure.

The pin 10 is of uniform diameter throughout, except near its lower end, where itis provided :with an annular groove 11, and is of such size as to be snugly receivedby'the with a longitudinal slot 12, as shown,,for

the reception of a nail, screw-driver or the like to give a handle to pull the pin outward in case it should become stuck in said perforations.

In its upper end portion it is laterally recessed to receive a stop pin 13, which prevents the separation of the pin from the plate after assembly. 7

To assemble,the catch 6 is first mounted jin slot 3 of flange 1, the pin 10 is then passed displacement of the said andthe flanges land 2 is such that when the stop pin l8 engages the lower face of the flange 2 the annular groo'v'ellof'the pin 10 will lie in the plane of the slot 3 so as to receive the catch 6 located iILSLlCl slot,

portion is received by the perforation in said flange and its stop pin '13 is in engagement with the lower face of the said flange 1, when the catch 6 will be movedto normal position, extendinginto the groove 11 of the pin 10 and preventing: longitudinal movement thereof.

To remove the chain it is but necessaryi to pry the catch 6 open, remove the terminal links from the pin 10 and then repeat the above described operation.

In order to obtain ease'in theiworking of i the catch 6, the upper and lower w-allsiof theslot 3 flare laterally outwardly and the catch 6jis correspondingly formed in wedgeshapein lateral cross-section, so that a very faces of saidcatch from. the walls of said slight, movement suflices I to disengagethe slot, allowing the catch to be moved freely without impediment on its fulcrum, this construction being shown in Fig. 7..

In the modification illustrated in.=Fig. 3, the construction and operation of'the device V are the same as in the above described pre-' I ferred form, excepting that they are ems bodied in a slightly different form of plate I intended to be used as a cleat to be attached to the side of a metal disk wheel having its outer portion near its felly curved or arcuate in form, and to this end,-

instead of having two perforated end flanges, it has a perforated lateral flange J r and is to be mounted onv the wheel by means of a bolt, not shown, adapted to pass through.

said perforation and into or through the disk wheel, not shown.

The pin 10 may secure the terminal por-- 7' tions of the chain in the plate by receiving f the. terminal linksthereof, as above "described, or may secure them therein injany other suitable manner.
